How to Bid a Drywall Job: Measure, Price, Win (2026)

To bid a drywall job, measure every wall and ceiling, turn the square footage into sheets with about 10% waste, add mud, tape and screws from manufacturer coverage rates, figure hanging and finishing hours from your crew’s real production, add overhead per labor hour, then divide your total cost by (1 minus your target margin). Write the finish level into the bid. Below is each step, the markup vs margin math and a complete worked bid for a 1,400 sq ft basement room.

Quick Answer

Price = (materials + labor + overhead) ÷ (1 − margin). At a 25% margin that’s cost ÷ 0.75, which is a 33.3% markup, not 25%. For a sanity check, hung and finished drywall usually lands around $1.50 to $4.00 per sq ft installed, with most jobs near $2.50. Prices vary by region, so check what drywall contractors near you charge and get current supplier quotes before you send a 2026 bid.

Where this comes from: I’ve spent 20+ years bidding residential remodels. In my work, drywall is usually one part of a bigger kitchen or bathroom bid, not a standalone sub job. The production numbers below come from trade sources and are labeled that way. The bidding math is the same math I use on every job.

What to Measure on the Walkthrough

You can’t price what you didn’t measure. Write these down room by room:

Wall area: perimeter × wall height. A 20 × 30 room with 8-ft walls is 100 ft × 8 ft = 800 sq ft.
Ceiling area: length × width. Same room: 600 sq ft.
Ceiling height over 8 ft. Taller walls mean taller sheets, more seams, scaffolding or a lift, and slower work.
Openings. Don’t deduct standard doors and windows on a small job; the cutout usually ends up as scrap anyway. Do deduct big openings like a garage door or a wide cased opening.
Outside corners, window returns and soffits. Each one is corner bead plus extra finishing time.
Board type by area. Moisture-resistant board in wet areas, Type X fire-rated board wherever the plans or your local code call for it. Check your local code.
Finish level and texture. Smooth Level 4, Level 5 for glossy or dark paint, or a texture to match.
Access. Stairs, a basement, a third floor or no place to stage board all add stocking time.

For whole-house new construction, FieldPulse publishes a rough check: living area × 3.8 for 9-ft ceilings, × 4.1 for 10-ft and × 4.5 for 11-ft, plus about 500 sq ft for a garage. Use it to catch a missed room, not to price the job.

On a remodel, also look hard at what’s behind the walls before you price. I’ve been burned by underbidding jobs where the hidden scope blew up once the walls came open. In the Pacific Northwest that’s usually rot from water getting in around windows and under sinks. Put an allowance or a clear exclusion in the bid for anything you can’t see.

Material Quantities With Waste

Start with sheets. A 4 × 8 sheet covers 32 sq ft and a 4 × 12 covers 48 sq ft. Add about 10% for waste, then round up:

Sheets = (total sq ft × 1.10) ÷ sq ft per sheet

Then the finishing materials, using manufacturer coverage rates:

Material	Coverage rate	Source
Joint compound (ready-mix)	About two 4.5-gal pails per 1,000 sq ft of board	USG
Paper joint tape	About 370 ft per 1,000 sq ft of board	USG data sheet
Screws, walls	16 in. spacing on wood or steel framing	USG
Screws, ceilings	12 in. spacing on wood or steel framing	USG

Screw count per sheet follows from the spacing. A 4 × 8 sheet hung horizontally on walls with studs 16 in. on center crosses 7 studs, with 4 screws down each one: 28 screws. The same sheet on a ceiling with joists 16 in. on center gets 5 screws per joist: 35 screws. Fire-rated assemblies can call for different fastener spacing, so follow the tested assembly on rated work.

Material prices move. These are typical 2026 ranges to check your supplier quotes against:

Item	Typical range
1/2 in. drywall, 4 × 8 sheet	$10 to $20
5/8 in. Type X, 4 × 8 sheet	$15 to $28
Joint compound, box or bucket	$12 to $25
Drywall tape, roll	$3 to $8
Drywall screws, box (about 150)	$7 to $15
Drywall lift or scaffold rental, per day	$30 to $120

The drywall calculator counts sheets, mud, tape and screws for a room, and the drywall mud estimator breaks out compound by coat.

Finish Level Sets the Labor

The Gypsum Association’s GA-214 standard defines six levels of finish. Name one in every bid, because “smooth walls” means different things to you and the homeowner.

Level	What it takes (flat joints)	Where it’s typically specified
0	Nothing	Temporary work, or finish not decided yet
1	Tape set in compound	Concealed areas like attics and above ceilings
2	Tape embedded and wiped, 1 coat on fasteners	Tile backer, garages, storage areas
3	Tape plus 1 more coat, 2 coats on fasteners	Under medium or heavy texture
4	Tape plus 2 more coats, 3 coats on fasteners	Smooth walls with flat paint, light textures
5	Level 4 plus a skim coat over the whole surface	Glossy or dark paint, harsh side lighting

Most residential living space gets Level 4. Here’s the trap: the GA guide says non-flat or dark paints aren’t recommended over Level 4. If the homeowner picks a semi-gloss or a deep color after you bid Level 4, the joints can show through. Ask about paint at the walkthrough, and price Level 5 as its own line when it’s needed, because that skim coat covers every square foot of the room.

Labor Hours From Production Rates

Labor is most of a drywall bid, and it’s where most bids go wrong. Price it from hours, not a guess.

Hanging. A long-quoted benchmark from a 2005 Walls & Ceilings column is that a good hanger can hang about 40 sheets in a day of eight-plus hours. Treat that as a starting point, not a rule. A 2026 Buildermuse article on crew productivity points out that sheet counts aren’t comparable when one crew hangs 4 × 12s and another hangs 4 × 8s. Ceilings, tall walls, lots of cuts and carrying board downstairs all slow it down.

Finishing. Finishing takes more labor than hanging. Market data in our pricing reference puts finishing at about 60% to 70% of total drywall labor. It also takes trips: at Level 4 you’re back for the tape coat, two more coats on flat joints and the sanding, with drying time between each. Plan for those trips even if each visit is short.

Your real rate beats any benchmark. Track sheets hung per crew-hour and finishing hours per job for a month. That one number will make your bids tighter than anything you read online.

Labor cost per hour is wage plus payroll taxes, workers’ comp, insurance and any benefits. Use that loaded number, never the bare wage.

Overhead and Markup vs Margin

Overhead is everything that keeps the business running but isn’t on this job: truck, tools, insurance, office, phone, marketing, your own admin time. Divide a year of overhead by the crew hours you bill in a year and you get an overhead rate per labor hour. The contractor overhead rate calculator walks through it.

Markup vs margin is where good tradespeople lose money. Markup is profit as a percent of cost. Margin is profit as a percent of price. If you want a 25% margin and you add 25% to your cost, you end up at 20%.

Target margin	Divide cost by	Same as a markup of
20%	0.80	25.0%
25%	0.75	33.3%
30%	0.70	42.9%

Price = cost ÷ (1 − margin). Check your numbers with the profit margin calculator.

Worked Bid: 20 × 30 Basement Room, Level 4

The job: finish a rectangular 20 × 30 basement room with 8-ft walls and a drywall ceiling. Framing, insulation and electrical are done by others. No soffits or wrapped windows, so no corner bead. Level 4 smooth finish, ready for the painter.

Areas: walls 800 sq ft, ceiling 600 sq ft, total 1,400 sq ft.

Sheets (4 × 8, 1/2 in.):

Walls: 800 × 1.10 = 880 ÷ 32 = 27.5, round up to 28
Ceiling: 600 × 1.10 = 660 ÷ 32 = 20.6, round up to 21
Total: 49 sheets

Finishing materials:

Mud: 1,400 sq ft ÷ 1,000 × 2 pails = 2.8 pails, × 1.10 waste = 3.08, round up to 4 pails
Tape: 1,400 ÷ 1,000 × 370 ft = 518 ft, × 1.10 = 570 ft, so two 500-ft rolls
Screws: 28 wall sheets × 28 = 784, plus 21 ceiling sheets × 35 = 735, total 1,519 screws, so 11 boxes of about 150

Labor hours:

Hanging: 49 sheets ÷ 40 sheets per hanger-day = 1.2 days, or about 9.8 hours. Add 20% for the ceiling and carrying board downstairs: 9.8 × 1.2 = 11.8, so bid 2 hangers × 6 hours = 12 hours.
Finishing: if hanging is about 35% of the drywall labor, the total is 12 ÷ 0.35 = 34 hours, so finishing is 34 − 12 = 22 hours, spread over about four trips.
Total: 34 hours.

Example rates (replace with yours): loaded labor cost $45 per hour, overhead rate $20 per labor hour, target margin 25%.

Line item	Qty	Unit cost	Total
1/2 in. drywall, 4 × 8	49 sheets	$15	$735
Joint compound	4 pails	$18	$72
Paper tape, 500 ft	2 rolls	$8	$16
Drywall screws	11 boxes	$10	$110
Drywall lift rental	1 day	$60	$60
Materials			$993
Hang labor	12 hrs	$45	$540
Finish labor, Level 4	22 hrs	$45	$990
Labor			$1,530
Overhead	34 hrs	$20	$680
Total cost			$3,203
Price at 25% margin		$3,203 ÷ 0.75	$4,271

Check the math: $4,271 − $3,203 = $1,068 profit. $1,068 ÷ $4,271 = 25% margin. $1,068 ÷ $3,203 = 33.3% markup. Round it to a clean number on the proposal if you like; round up, not down.

Check the market: $4,271 ÷ 1,400 sq ft = $3.05 per sq ft. That’s inside the $1.50 to $4.00 installed range, above the $2.50 middle. In this example the 20% slow-down for the ceiling and the overhead charged on every labor hour are what push it up, and a small single-room job has less footage to spread them over. Our drywall cost per square foot guide has more on where installed prices land. If you land far outside the range, recheck your hours before you touch your margin.

You can also check labor against sub pricing. Market rates for hang-and-finish labor run about $32 to $96 per 4 × 8 sheet at Level 4, with $56 typical. At $56, 49 sheets is $2,744. This bid carries $2,210 of labor and overhead before profit, so it isn’t out of line. Our posts on drywall labor cost per sheet and drywall taping cost per square foot break those rates down further.

If your state taxes materials, add it to the material line. If you haul off scrap, add a disposal line.

Common Drywall Bidding Mistakes

Bidding finishing as one trip. Level 4 is several visits with drying time between them. Your drive time and setup happen every visit.
Not naming the finish level. Write “Level 4, ready for primer” or “Level 5 skim coat” so there’s no argument at the walkthrough.
Bidding Level 4, then the client picks gloss paint. Ask about paint before you price.
Skipping texture matching. On repairs and additions, matching an existing knockdown or orange peel is its own line. Our guide to estimating drywall repair covers patch pricing.
Forgetting access and equipment. Ceilings over 8 ft, stairwells and third floors mean a lift or scaffold and slower hanging.
No allowance for what’s behind the walls. On older remodels, rot and out-of-plumb framing turn a clean hang into shimming and repair. Exclude it or carry an allowance.
Using the bare wage instead of loaded labor cost. The difference is your payroll taxes, comp and insurance, and it comes straight out of your profit.
Adding your margin percentage as a markup. A 25% markup is a 20% margin. Use the table above.

Being cheap isn’t the goal. A lot of contractors underbid to win the job and then make it back on change orders. Bid the full scope honestly instead. The client who values that is the client you want.

Presenting the Bid and Following Up

A drywall bid that wins is clear about what’s included. Put these in writing:

Square footage and rooms covered
Board type and thickness by area (standard, moisture-resistant, Type X)
Finish level, and texture if any
What’s not included: framing repairs, insulation, electrical box moves, primer and paint
Cleanup and scrap haul-off
Schedule, including drying time between coats
Payment terms and how change orders are priced

You can start from our drywall estimate template or run the job through the drywall installation cost calculator as a second check.

Then follow up. A lot of jobs are won on the second or third follow-up, not the first estimate. Most contractors send a bid and never chase it, so the one who follows up stands out as the contractor who has their act together. The hard part is remembering to do it when you’re on a jobsite all day. Send a short note a day after the bid, another a couple of days after they’ve looked at it, and a last one about a week out.

FAQ

How do I figure out how much to charge for drywall per square foot?

Build the price from your own materials, labor hours, overhead and margin, then divide by the square footage. Use the $1.50 to $4.00 per sq ft installed range only as a check. A per-square-foot number you copied from someone else carries their crew speed and their overhead, not yours.

Should I bid drywall per sheet, per square foot or by the hour?

Build it from hours either way, then quote the client a fixed price for the defined scope. Per-sheet pricing is common between general contractors and drywall subs. Hourly works for small repairs where you can’t define the scope up front.

How much waste should I add for drywall?

About 10% on sheets is a common starting point. Go higher on rooms with lots of angles, short walls or cutouts, and lower on big, simple rooms hung with long sheets.

Do I need a lift for drywall ceilings?

Not always, but on a full ceiling it often pays for itself. A drywall lift or scaffold rents for about $30 to $120 a day. At $60 a day, the lift costs less than two hours of a $45-an-hour helper holding sheets overhead. Put it on the bid as its own line.

What’s the quickest way to check a drywall bid?

Run the room through the drywall calculator for quantities and compare your per-square-foot price to the installed range above. If you’re far off, recheck your hours first.

Bid It Right, Then Chase It

Measure everything, count materials from coverage rates, price labor from real hours, add overhead and divide by (1 − margin). Then put the finish level in writing and follow up.
